SPECIFICATION forming part of Letters Patent No. 438,571, dated October 14, 1890.

Application iled July 30, 1890.

To all whom, it may concern:

Be it known that I, EDWARD J. BROOKS, a citizen of the United States, and a resident of East Orange, in the State of New Jersey, have invented a new and useful Improvement in Inking-Pads, of which the following is a specication.

This invention relates to felt pads primarily designed for use by postmasters for inking stamp-canceling and post-marking handstamps.

Heretofore such pads have been made with a top of thick ink-holding felt supported by an elastic body of roller composition or a gelatine compound, such as is used for printers inking-rollers, but serving exclusively to cushion the felt.

The objects of the present invention are, first, to furnish such pads with an elastic support that will so cushion the felt as to reduce noise and prevent injury to the stamps, and will at the same time insure more uniformlysecondly, to supplement such improved support with an outer portion of the said gelatine compound, to more securely attach the felt, and to render the pad more elastic, as hereinafter more fully set forth.

A sheet of drawings accompanies this specification as part thereof. v

Figure 1 of these drawings is a perspective vievvr of a round pad, illustrating this invention. Fig. 2 is a vertical section of the same. Figs. 3 and 4 are views similar to Fig. 2, representing additional species. Figs. 5 and 6 are perspective views of pads of other shapes, illustrating the same invention. Fig. 7 is a vertical section of the pad represented by Fig. 6. Figs. 8 and 9 are perspective and sectional views of another square pad, and Fig. 10 is a fragmentary perspective view illustrating the preferred mode of manufacture.

Like letters of reference indicate corresponding parts in the several figures.

In each of the inking-pads represented by the drawings a top layer A or A2 or AB or A4 or A5 of suitable felt is cushioned, as re` gards its center at least, by an elastic support B or B2 or B4 or B5, that is less pliable Serial No. 360,333. (No model.)

than the support composed wholly of roller composition or gelatine compound heretofore employed, but elastic enough to deaden noise and to prevent injury to the dies of stampcanceling and post-marking hand-stamps. The result is that when the pad is struck the felt does not sink in the middle or become dished and the die is more evenly inked than heretofore. The improved support may when confined to the center of the felt be composed of one or more layers of cork or the like'cut to the right size and shape; but I preferably employ ground cork, cork-dust, or shavings of cork embedded in gelatine compound, which cork mixture, as it is hereinafter termed, is much cheaper than cork and quite efficient. More or less elastic particles of other suitable substances may also be combined with gelatine compound in like manner to form a less pliable support and to cheapen the pad.

In the pad represented by Figs. l and 2 an outer portion C of the more elastic gelatine compound embraces the edges of the felt A and the sides and bottom of the less pliable elastic support B of cork mixture, and a thin bottom layer D of felt protects the pad against adhering to a desk or the like on which it is used.

Fig. 3 represents the same pad as Figs. 1 and 2 with said bottom felt D omitted. A coating of suitable varnish renders the outer surfaces of the gelatine compound sufficiently non-adhesive.

Instead of so inclosing the improved elastic support, the base of the pad may be composed Wholly of such cork mixture, as represented at B2 in Fig. 4, and in any make of the improved pad two or more top layers of felt may be employed, if preferred, as represented by the line at A2, Fig. 4:.

Such pads are molded of the desired shape, and as illustrated by Fig. 5 the top felt A3 may be square, (or of other shape,) as Well as round, with a base Z of corresponding shape, and of any of the structures represented by Figs. 2, 3, and 4.

In each of the species represented by Figs. G to 9, inclusive, the pad is composed of a round or square top 'felt A4 or A5, an underlying corkemixture'support B4 or B5, an elastic binding portion C2 or Cg'of the gelatine compound, a rigid casing E or E2 of Wood, metal, or the like, and a bottom felt D2 or D3, applied to such casing. As thus combined with a rigid casing, the top felt may project, as at A4, Figs. 6 and 7, or may be iush (or sunken) as at A5, Figs. 8 and 9.

In the preferred mode of making such pads the cork mixture is molded in flat sheets, as represented by a fragment at B', Fig. lO, and pieces of proper size and shape for the supports B B2, tbc., are stamped therefrom, and introduced into the molds or into the casings E E2 in proper position. When the gelatine compound is cast.around such cork-mixture supports, as at C C2, dre., the gelatine cornpound in the latter unites with that of the outer portion and the Whole is inseparably joined in one mass. The gelatine compound in the cork mixture serves also to adhesively attach the top felt at practically every portion of its area and not only at its margin.

.Details which have not been specified may be of any approved description, and I do not limit my respective claims as to details cxoept as therein expressly stated.

Having thus described such inking-pads, I claim as my invention and desire to patent under this speciication Y l. An inking-pad having an ink-absorbent top of suitable felt cushioned by an elastic i
